 Description   

We don't currently build with MemorySanitizer (note that this is distinct from AddressSanitizer) because MemorySanitizer requires an instrumented libc C++ standard library.

We could potentially make it work well enough though if we vendored in a copy of libc++ and built it with msan as well.
